Prumo is a new type system, based on a unique skeleton that flows, like a pendulum, from high contrast to low contrast. It’s a sort of typographic journey, from the 18th century typefaces to the 19th century slab serif typefaces, gathering information from the Scotch Roman fonts on its journey. Prumo is a type family with classic proportions that takes advantage of the recent type production technology while looking carefully at the most important historical references.
